Abstract

The invention belongs to the technical field of biological detection, and discloses a biological detection device which comprises a detection mechanism and a driving mechanism, the detection mechanism comprises a bearing plate, a containing plate and a circulation plate which are stacked and coaxially arranged, the containing plate and the circulation plate are both borne on the bearing plate, and the containing plate is located between the circulation plate and the bearing plate; a first through hole is formed in the containing plate, the first through hole is communicated with the side face of the containing plate, so that a containing groove is formed between the circulation plate and the bearing plate, the test paper box can be inserted into the containing groove, a circulation channel is formed in the circulation plate, one end of the circulation channel is communicated with the outside, and when the test paper box is inserted into the containing groove, the first through hole is communicated with the side face of the containing plate. A sample pad of the test paper is positioned on one side far away from the axis of the accommodating plate, an absorption pad of the test paper is positioned on one side close to the axis of the accommodating plate, the other end of the flow channel is aligned to the sample pad, and the driving mechanism drives the bearing plate, the accommodating plate and the flow plate to rotate around the axis, so that the sample liquid is subjected to sufficient biochemical reaction, and the accuracy of a detection result is improved.

Description

technical field [0001] The present invention relates to the technical field of biological detection, and in particular, to a biological detection device. Background technique [0002] With the rapid development of biological detection technology, paper-based microfluidic chips are more and more widely used in the field of biological detection. Because paper materials have the characteristics of low price, rich variety and high biocompatibility, paper-based microfluidic chips used for biological detection are widely used. The experimental cost of the fluidic chip is low. [0003] The test paper of the paper-based microfluidic chip includes a sample pad and an absorption pad. During the detection, the sample is dropped onto the sample pad, and the sample liquid flows from the sample pad to the absorption pad under the drive of the capillary force of the test paper. Biochemical reactions can occur during the flow from the sample pad to the absorbent pad, and the detection resu...
